Infrequently performed studies in nuclear medicine: Part 1.

Nuclear medicine is a diverse field with a large number of different studies spanning virtually all organ systems and medical specialties. Many nuclear medicine procedures are performed routinely; others may be performed only rarely, sometimes less than once per year. The infrequent nature of many studies makes it challenging to retain relevant knowledge and skills. This 2-part article provides a review of several infrequently performed studies. The topics discussed in Part 1 include dacroscintigraphy, LeVeen shunts, scintimammography, right-to-left shunts, left-to-right shunts, and heat-damaged red blood cells. After reading this article, the reader should be able to list and describe the indications for each study, list the doses and describe their proper method of administration, and describe problems that may arise during the imaging procedure and how they should be handled.
